GEORGE L. CUMMINGS, OF NElV YORK, N. Y.

CLOCK-CHIME.

SPECIFICATION forming part of Letters Patent No. 474,371, dated May 10,1892.

Application filed January 24, 1889. Renewed March 14, 1891. Serial No.884,990. (No model.)

To all whom) it may concern:

Be it known that I, GEoRcE L. CUMMINGS, a citizen of the United States,residing at New York city, in the county and State of New York, haveinvented certain new and useful Improvements in Chime-Clocks; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention is a contrivance of clockchimes for being moved along thehammer so that all the bells of the chimes may be struck successively byone hammer, which is a much simpler and cheaper construction andarrangement of mechanism than the common arrangement of a hammer to eachbell, all as hereinafter fully described, reference being made to theaccompanying drawings, in which Figure 1 is a side elevation of theworks of a chime-clock of my invention with the chime arranged forrotatory movement. forbringing the bells to the hammer successively.Fig. 2 is a front elevation of the same with a part in section. Fig. 3is a front elevation of part of the clock-works, showing the chimearranged for reciprocatory movement of the chime in which the inventionmaybe carried out, although the rotatory movement is the best. Fig. 4 isa detail of the contrivance for mounting the bells as in Figs. 1 and 2;and Fig. 5 represents an arrangement of the bells so that two may bestruck at once by the hammer.

With any part of the striking-train of a clock, but preferably with theprime moving wheel a, I gear a driving-shaft b for working the chime ofbells c by a suitably-timed or graduated train at e f g for the motion Iwant, according to the number of bells to be employed in the chime, andconnect the bells with said shaft in any approved way, so that they willbe moved successively along past the hammer h when it is Working and bethereby struck in succession, preferring to connect them by radial armst of a hub 7,021.1- ried by said Wheel for rotatory motion, as in Figs.1 and 2; but they may be mounted on a reciprocatory mover 7;, havingsuitable crankand-rod connection Z m with said shaft, as in Fig. 3, orotherwise, as desired. The rotatory arrangement affords a greater rangeof movement and consequentlyenables a greater number of bells to be usedin the chime with a given range of the driving-train than thereciprocatory movement and is preferred for that reason, and, besides,it is somewhat simpler to construct; but with either way of producingthe movement clocks can be made with equally efficient chimes muchcheaper than in the common arrangement of stationary bells and a hammerto each bell, which makes chime-clocks so expensive that they are notmuch used.

When I use gong-bells, I prefer to mount themin the rotatory arrangementby the bent arms 2', edgewise parallel to the shaft 1), by which theycan be placed closer together and therefore in a smaller circle, and Imount these arms in the hub, so that they can be turned to hold thebells obliquely, with checknuts n to secure them in any position; but Ido not limit myself to any particular form of bell or way of mountingthe same.

The driving-train for the chime is mounted in any approved frame 0 thatis adapted to be applied to clocks in use by fastening it to the insideof the back of the clock-case; but in the making of new clocks it willbe preferable to adapt the clock-frame for reception of the chimeattachment.

If desired, the bells may be arranged in pairs with the members of eachpair in such close proximity that both will be struck at the same timeby the hammer, as represented in Fig. 5. This adjustment of the bellsmay be facilitated by the bent supporting arms.

What I claim, and desire to secure by Letters Patent, is

1. A clock-chime consisting of moving bells passing along the hammer soas to be successively struck by a single ordinary clockhammer,substantially as described.

2. The combination, with the bell-hammer of a clock, of a movable chimeof bells, and bell-operating mechanism connected with the striking-trainof the clock and moving the bells successively to the hammer whenstriking, substantially as described.

3. The combination, with the bell-hammer of a clock, of the rotatorychime of bells, and

bell-operating mechanism connected with the bells are placed in pairs juxtaposited so that striking-train of the clock and moving the thehammer strikes both bells of a pair tobells successively to the hammerwhen strikgether, substantially as described.
